In view of the above-described problems, it is one objective of theinvention to provide a combination of a motor and a wind wheel that hasa simple structure, easy and firm installation, high reliability, goodaxiality between the shaft and the wind wheel, and little oscillation ofthe wind wheel.

To achieve the above objective, in accordance with one embodiment of theinvention, there is provided a combination of a motor and a wind wheel.The motor comprises a shaft comprising a plurality of mounting holes.The wind wheel comprises: a mounting plate, a plurality of wind blades,a first through hole, and a boss. The wind wheel is arranged on themotor. The wind blades are arranged on the mounting plate. The firstthrough hole is disposed on a middle part of the mounting plate. Theboss is disposed on the mounting plate outside the first through hole. Asecond through hole is arranged on the boss. The mounting holes arearranged on the shaft. The shaft passes through the first through hole.A screw passes through the second through hole and is inserted into themounting hole for fastening the wind wheel on the shaft.

In a class of this embodiment, the mounting hole is a circular recess ora square notch.

In a class of this embodiment, a neck is arranged on the shaft. A clampspring is inserted into the neck for fastening the mounting plate of thewind wheel.

In a class of this embodiment, four mounting holes are provided; everytwo mounting holes are arranged in a group; and two groups of themounting holes are distributed on two ends of the shaft, respectively.

Advantages of the invention are summarized as follows:

A plurality of mounting holes is arranged on the shaft. The shaft passesthrough the first through hole. The screw passes through the secondthrough hole and is inserted into the mounting hole for fastening thewind wheel on the shaft.

The invention has a simple structure, easy and firm installation, highreliability, good axiality between the shaft and the wind wheel, andsmall oscillation of the wind wheel.

The neck is arranged on the shaft. The clamp spring is inserted into theneck for fastening the mounting plate of the wind wheel; therebypreventing the wind wheel from moving axially, and reducing thetechnical difficulty of opening a mounting hole.

Four mounting holes are provided, every two mounting holes are arrangedin a group, and two groups of the mounting holes are distributed on twoends of the shaft, respectively. The structure is reasonably designed,and meets requirements of two different sizes.
